I base my enthusiasm on all the recent developments
1) the durability testing proving out decades of operable time 2) the timeline to releasing the 2 protos with specs to the market as end of 1st quarter 2015 (adjusted from end of 2014 due to OpSIS chip receipt being delayed approx 3 months)
you can be a bear, and other like myself and coolair can be bullish to get in ahead of the expectations here
